TO ALL WHOMIT MAY CONCERN: v

Be it known that I, Wi P. BRooKs, of Bloomington, in the county of'McLean', and State of'Illinois, have invented a new and improved Draugh-t-Attachinent or Evener for Vehicles and implepents drawn by horses; and do hereby declare that the following is a. description thereof, which will enable others skilled in the art to make anduse thesame, reference being had to-the accompanying drawings forming part of this specification. This invention relates to a new and improved draught-attachment or evener for vehicles and implements which are drawn by: horses, and it consists ina, peculiar construction of'the device, as hereinafter fully shown and described, whereby the draught may be equally divided between the'jtwo or three horses which may be appliedto it, or an advantage (ease of draught) allowed either horse, if necessary to do so.

. The invention may, by a very simple adjustment of parts, be adapted for either two or three horses, and

attached to vehicle or implement, so as to have a flat, or edglewise' positionnas hereinafter fully" shown and described.

In the accompanying sheet of drawings-- Figure 1 is a plan or top view of my invention adaptedfor three horses, and having ails-twist: position. Figure 2, a plan or top view ofthe same, alsoadapted for three horses, but having an edgcwigse position. t Figure 3, a plan or top view of the same, adapted for two horses, and having auiedgewisejiosition. Figure 4, a transverse section of fig. 3, taken in the line a: x. 4

Similar letters of reference indicate corresponding parts;

A isa wooden bar, of flat form, that is to say, considerably wider than it is thiclwand of 'sufiicient length r to admit of three whifiie-trees being attached for three horses. Torthe centre of the bar A thereis secured,

by a bolt, (1, an upright wire bar, 13, the upper part of which is perforatedwith a series of, holesQb, to-receive a bolt, 0, which securcsan eye or loop, (1, to the bar B, said eye or loopbeingadjusted higher or lower on B, by

passing the bolt 0 through a higher or lower hole, 6, as will be fully understood by 'referring to fig. T0 each end of the bar A, there is secured, by bolts, an iron bar, 0. These bars are bent in right-angular form, and

provided with hooks d cl, at their ends. I

These bars C thus bent, are capable ofbeing adjusted to two sides of the bar A, to wit to one of the hroad sides 0, and to" one of the narrow sides or'edgesf. By this ineans the hooks d may be tit-the front edge of the broad side e, and the hooks d'f at the under side of the same, or considerably below the ler'el or -plane of the hooks d. i

The bars C znay be adjusted'nearer to or fartherfronrthe centre of'the bar A, as desired; di

holes g,being made in the bar A, to admit of this being readily done, (scc 1.) i

The bolt a has an eye, 7;,- at its rear end, in which a ring, 2', is fitted to secure the barAto the olevis of any implement, or to a vehicle. A whifile-trec is attached to each hook dof the bars 0, whcn'thc bar is used flat wise, as shown in fig.,1, and a ivhifile-tree is attached to thc eye or loop 01 of the central bar B.

, By referring to fig. 4, it will be seen that the bar B serves as a lever to the centre horse, and places him in the samefposition, as regards leverage, as the other two horses. The draught,therefore,'is equally divided 7 between the three horses,.when the bars C are adjusted to bar A'at equal distances from'its centre.

Ifit should be necessary to favor either the oil' or near herseit may readily be done, moving the bar G to which the horse not to befavored is attached, more or less inward, 'so as to decrease his leverage on bar B. ,The centralhorse attached to bar B may he treated inla like manner, by shifting the eye or loop at higher or lower on bar B. 'Taking the eye It of bolt a as a fulcrum, and the distance of the hooks d or d from V a central line on A, parallel with its sides, and passing through the fulcrum, as equivalent to the distance of said hooks from thet'ulcrurn, it will be seen that, by having the distance from the eye or loop 01 to the fulcrum just double the distance each hook d or d" is from tbe central line on her-A, the drought will be equalised between the three horses.

'In order to adjust the bar A edgewise, as exhibited in figs. 2 and 3, the position'of bar B is shifted, was to extend upward from the narrow side or edge j, the end whiflie-trees, in this case, being attached to the books 11'],

and arranged substantially in the manner as and for the purpose set forth now 2 In converting the device into a. two-'hor se evoner, all that is-requi red is to remove the'bar B, and adjust the bar A, so that the hooks d end will be upp'rmost', or attho upper edge of'tho bar A.

' Having thus described my invention; what I claim as new ginnd desire to secure hy Letters Patnt, is-

- A draught-attachment or owner, composed of a. ba1', A, provided with bars 0, having hooks dd, eith'r or both, at its ends, in connection with the central har B, with adjnstableieye or loop 01, attached, all constructed W. P. BROOKS. Witnesses:
